(

)

Default constructor.

Member Function Documentation

gridLines()

bool sf::Draw::gridLines	(	QPainter &	painter,
		EGridOrientation	go,
		const QColor &	color,
		const QRect &	bounds,
		double	start,
		double	stop,
		unsigned	digits
	)		const

Parameters

painter	Painter context.
go	Orientation.
color	Color of the grid lines.
bounds	Area boundaries for the ruler.
start	Start value of grid lines.
stop	Stop value of grid lines.
digits	To make the grid correspond with the ruler when vertical.

Returns

True on success false in case of an exception.

ruler()

bool sf::Draw::ruler	(	QPainter &	painter,
		ERulerOrientation	ro,

area	Area available to paint texts on.
start	Start value of ruler.
stop	Stop value of ruler.
digits	Amount of significant digits or resolution of the printed values.
unit	unit string.

Returns

True on success false in case of an exception.

textCross()

bool sf::Draw::textCross	(	QPainter &	painter,
		const QRect &	bounds,
		const QString &	text,
